Does having adjacent connectors that close together on the motherboard impact signal timing? 8-). If you don't like the idea on that basis, then I could live with right-hand riser to go with a seperately purchased left-hand riser; I can get a left-hand riser anywhere... I think the biggest issue will be that the card will end up facing chip-side-down rather than chip-side-up, as for most cards, so the heat disapation will be towards motherboard components that may also want to be disapating heat into the same small areas there, between-card-and-motherboard. I think you can make the argument, though, that you will have that same problem with any card, even if it's right-side-up, because of it being parallel to the motherboard and the case top. Now to find a motherboard that can handle 1G SIMMs, where the SIMM connector hardware is at a steeper angle than normal so that you can fit 4G in a 1U case... ;^). -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
